JBL ProFlora CO2 Count Safe 2

Bubble counter featuring a backflow prevention mechanism.

Key Features:
• Easily regulate CO2 levels: this bubble counter with backflow prevention allows for precise dosing of CO2 in your aquarium.
• Simply fill the bubble counter with water, connect it to your CO2 system and diffuser with a hose, and secure it outside the aquarium using either 2 suction cups on the glass or 2 screws on the furniture.
• Simple bubble observation: CO2 bubbles are easily visible and countable, with no risk of backflow due to the integrated check valve, compatible with all standard CO2 systems.
• The reliable hose screw connection ensures that hoses remain securely attached, preventing unintentional disconnections.
